mod 24.1 worksheet: 1) awareness
2) a pseudoscientific claim appears to be based on science, but is not.
3) mood rings; horoscopes.
4) temperature, blood pressure, and the effectiveness of medicines.
5)
Circadian: 24-hour biological rhythm that is based on light and dark cycles. Example: sleep/wake cycle;
Ultradian: biological rhythm that occurs many times per day. Example: sleep cycle, hunger;
Infradian: biological rhythm that occurs monthly or seasonal. Example: a woman's menstrual cycle, bear's hibernation, leaves changing color.
mod 24.2 worksheet: 1) Sleep deprivation may contribute to any of the following: irritability, confusion, hypertension, Reduced performance and lack of concentration cause impaired learning, depression, Increased mental illness, Decreased immune system function, Increased pain perception, Decreased ability to metabolize glucose and an increased risk of diabetes., Less than five hours of sleep per night increases the risk of high blood pressure or worsening blood pressure. In a study at the University of Chicago, researchers found that for every hour sleep was reduced, the risk of high blood pressure increased by 37%., May trigger the release of stress hormones and an increased risk of heart attacks and strokes., An increased risk of breast and colon cancer. Melatonin fights abnormal cell growth, especially in breast cancer and colon cancer. Since melatonin is released at night, less sleep means less melatonin. Thus, a reduced cancer-fighting ability., Increased car accidents and occupational accidents, Increased inflammation. Chronic or systemic inflammation can cause a variety of diseases and conditions, During a 5-year study, researchers found extremes in sleep duration are related to more abdominal fat in individuals younger than 40 years of age. While six to seven hours were considered normal, the extremes were defined as five hours or less and eight hours or more. Individuals with less sleep had a higher body mass index (BMI). Excess abdominal fat is a known risk for many diseases.
2) preservation and restoration
3) the hypothalamus is the sleep control centre of the brain
4) Melatonin is the chemical in the brain that regulates biological rhythms
5) sleep cycles are 90-minute ultradian cycles (because they happen more than once a day
6) Sleep Stage 1: ~5 minutes; muscle contractions, sensation of falling Sleep Stage 2: 20 minutes; eye movement stops, brain waves become slower Sleep Stage 3: 30 minutes; children experience bedwetting, sleepwalking, and night terrors REM sleep: 25% or 100 minutes of normal sleep cycle; body is temporarily paralyzed, breathing becomes faster, eyes move under eye lids
